DisplayPort Technology — Heir Apparent to VGA?

For the last 20 years we have connected our monitors to our computer systems having the confidence that upon turn-on, we could surf or create with never a consideration of whether the display would operate satisfactorily. VGA (Video Graphics Adaptor) technology enabled us to do that with CRTs as well as with flat panel displays. Now, however, the viewing benchmarks are being reset, as are system design considerations. There’s a new interface on the horizon called DisplayPort!

Optoelectronic System Measures Distances to Multiple Targets

This system operates at an update rate >10 Hz. NASA’s Jet Propulsion Laboratory, Pasadena, California An optoelectronic metrology apparatus now at the laboratory-prototype stage of development is intended to repeatedly determine distances of as much as several hundred meters, at submillimeter accuracy, to multiple targets in rapid succession. The underlying concept of optoelectronic apparatuses that can measure distances to targets is not new; such apparatuses are commonly used in general surveying and machining. However, until now such apparatuses have been, variously, constrained to (1) a single target or (2) multiple targets with a low update rate and a requirement for some a priori knowledge of target geometry. When fully developed, the present apparatus would enable measurement of distances to more than 50 targets at an update rate >10 Hz, without a requirement for a priori knowledge of target geometry.

Large Solar-Rejection Filter

This lightweight filter comprises a multilayer spectral coating on a flexible membrane. NASA’s Jet Propulsion Laboratory, Pasadena, California An optical filter consisting of a multilayer spectral coating on a flexible membrane has been designed to be placed in front of the 200-in. (5.08-m) Hale telescope on Mt. Palomar. The filter is intended to protect the telescope against solar radiant flux and limit solar heating of the interior of the telescope dome while transmitting light at the 1,064-nm wavelength of the Mars Laser Communication Demonstration.

CMO Development Program

A Complex Monolithic Optics (CMO) Development Program has been announced by Agilent Technologies Inc. (Santa Clara, CA). The program offers customers the opportunity to incorporate the latest high-precision optics design technology into their optical system designs. Agilent developed CMOs to address the needs of interferometry applications where system stability and minimal downtime are critical. CMOs are stand-alone optical assemblies that are created when multiple discrete optics are bonded together into a single, pre-aligned optical structure.

Metal Marking System

Epilog Laser (Golden, CO) offers the FiberMark Laser System, a piece of equipment that allows users to mark directly on metal surfaces including titanium, steel, aluminum, carbide, alloys, brass, and more. The piece of machinery can mark all types of metal with barcodes, text, logos, and other graphics, using a beam of light as the engraving tool. The FiberMark has a flying optic beam delivery system, stainless steel bearings, a large 24 in. by 12 in. work area, and compatibility with most software packages. It has an optional floor stand, rotary attachment, and air compressor.

Full-Color LED Package

OPTEK Technology (New York, NY) has developed a full-color surface mount LED package called the OVSPRGBCR4. The package offers RGB color capabilities, a high CRI rating, and full 130° viewing angle. Applications for the OVSPRGBCR4 include automotive interior and exterior lighting, architectural indoor and outdoor lighting, LED backlighting, and general illumination. The OVSPRGBCR4 has a DC forward current of 250mA, a peak pulsed forward current of 500mA, and a thermal resistance of 20K/W. Typical luminous flux for the red, green and blue LEDs is 21 lm, 32 lm, and 7.5 lm, with a typical on-axis intensity of 7cd, 11cd, and 2.8cd, respectively. Maximum rated junction temperature is 125°C and the operating temperature range is -40°C to +100°C.
